Abstract
The disclosure is related to a method for manufacturing touch-sensitive element on a polarizer, and a polarization device made by the method. In one of the embodiments of the invention, a polarizing substrate is firstly prepared. The method then coats first transparent conductive material onto the substrate, and uses a patterning process to form multiple sensing areas and wiring areas. There are continuous paths and adjacent non-continuous paths are existed in between the sensing areas. A bridged insulating layer is formed as processing the step for spray-coating or inject-printing insulating material upon the areas of the non-continuous pads. A bridged conductive layer is formed upon the insulation layer as spray-coating or inject-printing a second transparent conductive material there-on. The bridged conductive layer is to electrically connect the non-continuous pads. The method is therefore forming the polarization device with the touch-screen elements.
